This integrated circuit is intended for GPS receiver applications. The dual

conversion design is implemented in Motorola’s low–cost,

high–performance MOSAIC 5 silicon bipolar process and is packaged in a

low–cost surface mount LQFP–48 package. In addition to the mixers, a

VCO, PLL, Crystal Oscillator, A/D converter and a loop filter are integrated

on–chip. Output IF is nominally 4.1 MHz.
